Psychoactive substances
Psychoactive substances are chemicals that affect the brain and alter mood, perception, or behavior. They can come from natural sources, like plants, or be synthetically made. Common examples include caffeine, alcohol, nicotine, and illegal drugs like marijuana and cocaine. These substances work by changing how brain cells communicate, which can lead to feelings of euphoria, relaxation, or stimulation. While some psychoactive substances are used for medical purposes, others can be addictive or harmful if misused. Understanding their effects and risks is important for informed decision-making about their use.
